Fracture Characteristics of Polyurethane Grouting Materials Based on Acoustic Emission Monitoring
In this study, 16 groups of tests were designed by the orthogonal test method, and a PU grouting material was prepared, which can be used for the construction of sealing wall in mined-out area of coal mine. The basic properties of the material were measured. Firstly, the viscosity of four groups of...
